Abstract: PROBLEM TO BE SOLVED: To remove effectively an aluminum ion by catching selectively that by a method wherein a water current is made to permeate a capture filtration layer with a chelate resin being one kind of ion exchange resin having preferential capture force to an aluminum ion by having selectivity for a metallic ion. SOLUTION: A cartridge 4 disposed inside a purification apparatus body 2 is composed of a filter and absorptive layer part as an upside part and an aluminum ion capture filter part as a lower part, and both parts are attached, detached and fixed with a screw part 9. A water current 1 permeates an absorption layer 7 of an activated carbon material from a filtration layer 6 of an antimicrobial filter material or the like. After removing chlorine, chlorine odor, and chlorine compounds, the water current 1 permeates a capture filter layer 10 with a chelate resin. Herein, an aluminum ion is selectively captured and removed. That is, metallic ion capture characteristics of the iminodiacetic acid type chelate resin to be used make useful ions of calcium or the like pass, and make the aluminum ion wanted to be removed capable of being preferentially captured.

Abstract: An article is disclosed comprising a substrate of glass, plastic, metal, organic polymer coated substrates and inorganic coated substrates, wherein at least a portion of the surface of the substrate is treated with a composition comprising a mixture of perfluoroalkylalkylsilane and a completely hydrolyzable silane. The perfluoroalkylalkylsilane provides rain and soil repellency to the substrate surface, while the fully hydrolyzable silane hydrolyzes and condenses to form silica, which imparts resistance to weathering and abrasion, thus improving the durability of the rain and soil repellency properties. The method of providing such a durable rain and soil repellent surface comprises contacting the substrate surface with a composition comprising perfluoroalkylalkylsilane and fully hydrolyzable silane, and may include first depositing a layer of silica on the substrate surface, then contacting the substrate surface with a composition comprising perfluoroalkylalkylsilane and fully hydrolyzable silane.

Filed: 1988-12-27
Abstract: PURPOSE:To prevent an abnormal working state of an electronic equipment which is caused by the temperature change by informing a fact that the ambient temperature detected by a temperature detecting means has reached a prescribed level that effects the electronic parts. CONSTITUTION:A CPU 7 inputs the ambient temperature data detected by a temperature detecting element 10 at each prescribed time and decides whether the ambient temperature is kept or not within a working environmental temperature range of an electronic equipment 1 that is previously set in response to the allowable working temperatures of such electronic parts as a display part 3, the CPU 7, a memory 9, etc., which are all under working. If so, the ambient temperature is continuously monitored. If not, it is decided whether the ambient temperature is kept within the working environmental temperature range or not with the second input of the ambient temperature data. If so, the temporary abnormality due to the noises, etc., is decided. If not, this fact is displayed at the part 3 and at the same time a buzzer 13 is actuated. Thus it is possible to prevent the inaccurate measurement of temperatures and the malfunctions due to the use of electronic parts outside the working environmental temperature range.
